You really want a clip on for this application? I assume this is for hunting too which I would guess maxes out at 60-70 yards tops? Seems like a Halo or Reap thermal scope and a Radius or Raptar range finder would be a better option. Or even one of the Pulsars with an on board range finder. Looks like the drop gets pretty substantial after 40-50 yards. But maybe a clip on is better for your application.

@Eliteuas. He’s shooting about same velocity as you I think and may have some insight.
